"Though we still have a long way to go, we're seeing some early progress," the company notes in a Google+ post.

Some of the highlights:

21% of the tech hires Google made last year were women and the overall number of women in technical roles went up by 1%.

This year, 22% of software engineers hired through campus outreach were women— more than the percentage of women pursuing CS degrees today (18%)

The increase in Black and Hispanic Googlers outpaced Google's hiring growth overall— but they still make up just 2% and 3% of the company, respectively.

Google recently pledged to spend $150 million on diversity initiatives over the next year, like expanding its formal Diversity Core program for employees, recruiting from increasingly varied sources, and working with partners to change the perception of computer science.

By attacking tech's homogeneity from many different angles, Google hopes to slowly but steadily change the status quo.

"We're all terrible at it," chief business officer Omid Kordestani said on stage about diversity in the tech community at the recent Code Conference. "And we have to be honest about it. There's not a silver-bullet answer here."
